    摘要： A process of producing a nonaqueous secondary battery comprising the steps of disposing a separator between a member containing a silicon-based material and a positive electrode, together with interposing a metallic lithium layer between the separator and the member to obtain an assembly, and aging the resulting assembly for a prescribed period of time to alloy lithium with the silicon-based material. Lithium alloying is preferably performed to a degree such that the amount of lithium in the silicon-based material is 5% to 50% based on the theoretical initial charge capacity of silicon. When the positive electrode has a lithium-containing active material for positive electrode, lithium alloying is preferably performed to a degree satisfying formula (1): 4.4A−B≧C, where A is the number of moles of silicon in the member containing the silicon-based material; B is the number of moles of lithium in the lithium-containing active material for positive electrode; and C is the number of moles of lithium to be alloyed.

    摘要： A negative electrode 10 for a nonaqueous secondary battery has an active material layer 12 containing active material particles 12a. The particles 12a are coated at least partially with a metallic material 13 having low capability of lithium compound formation. The active material layer 12 has voids located between the metallic material-coated particles 12a with a void fraction of 15% to 45%. The metallic material 13 on the surface of the particles is preferably present throughout the thickness of the active material layer. The active material particles 12a are preferably of a silicon-based material. The active material layer 12 preferably contains 1% to 3% by weight of an electroconductive carbon material based on the weight of the active material particles 12a.
